FIELD: process engineering.
SUBSTANCE: proposed tool head comprises body with guide roller with support elements fitted offset on body end face to revolve about body lengthwise axis, and cutting element. Note here that support elements are fitted regularly to slide on cylindrical surface of guide roller, each intended for interacting with billet inner rough surface. Tool head additionally comprises support roller, designed similar o guide roller to interact with machined surface while guide roller incorporates at least one braking means made up of spring-loaded friction element from high-friction material arranged on its outer side to interact with billet inner surface. Each said support element represents a ball or roller.
EFFECT: expanded performances.
